Nice to see Asirra available and ready to add to web sites...


Asirra is a human interactive proof that asks users to identify photos of cats and dogs. It's powered by over two million photos from our unique partnership with Protect your web site with Asirra — free!

The JavaScript works in all major browsers; it has been tested in IE6, IE7, Firefox 2, Safari, and Opera 9.
